v0.7.0

This release adds the optim interface for nonlinear optimization problems and two supported implementations: scipy_optimize based on the SciPy package and optim_jl based on the Optim.jl package.

To see how to use this interface, please refer to the example scripts:

• examples/lang_julia/call_optim_rosenbrock.jl
• examples/lang_python/call_optim_rosenbrock.py
